The utility model mainly consists of a connecting-tripping device 1, a bushing pump plunger 2, a bushing pump barrel 3, a shell 4 of the hydrocyclone, a main body 5 of the hydrocyclone, the bushing pump barrel 6, the bushing pump plunger 7, a bridge passage 8, a plunger 9, the pump barrel 10 of an integral barrel pump, the plunger 11 of the integral barrel pump, the pump barrel 12 of the integral barrel pump, the bridge passage 13 and a packer 14, is mainly used for the down-hole oil and water separation of the oil well pump, and has the advantages of good oil and water separating effect, continuous oil-water mixture separation in a wellbore and simple operational principle.
Description
Technical field: the utility model relates to oil field development oil production technology technical field, belongs to a kind of oil field underground oil-water separator.
Background technology:, enter the ultra-high water-containing mining phase along with the prolongation of oilfield exploitation time; In order to slow down the speed that crude output successively decreases, need improve constantly the oil field total fluid production, but the oilfield collection is failed the needs that can not satisfy extract with water treatment capacity.Underground oil-water separates the same-well injection technology of adopting can realize water-oil separating in the down-hole, and low moisture mixed liquor is lifted to ground, and the moisture mixed liquor of height is recycled into a certain stratum in the well, as water layer or scrap in the layer; Therefore, the surface water treating capacity of oil well produced liquid greatly reduces, and the oil extraction cost reduces significantly, thereby dead well is resumed production, and the underground oil-water isolation technics seems particularly important in Oilfield developing is used.The conventional pumping unit well can not be at the continuous lifting liquid of up-down stroke, what foreign oil company such as Canada adopted at rod-pumped well in the world is to utilize the action of gravity principle to carry out underground oil-water to separate, and its oil-water separation directly is subjected to the influence of well deliverability.
Summary of the invention: the purpose of this utility model be to overcome the deficiency of above-mentioned prior art and develop a kind of can guarantee oil well pump up-down stroke continuous to the hydrocyclone feed flow, make hydrocyclone oily-water seperating equipment under the continuous liquid supply oil pumping well of the continuous realization water-oil separating in down-hole, this is novel mainly by on-off connector, the bush pump plunger, the bush pump pump barrel, the hydrocyclone housing, the hydrocyclone main body, the bush pump pump barrel, the bush pump plunger, passageway bridge, plunger, whole tube pump pump barrel, whole tube pump plunger, whole tube pump pump barrel, passageway bridge, packer is formed.Wherein the on-off connector lower end connects by the upper end of screw thread with the bush pump plunger.Thread connection is passed through in the upper end of the lower end of bush pump plunger and hydrocyclone housing.The lower end of hydrocyclone housing connects by the upper end of screw thread with the bush pump plunger.The lower end of bush pump plunger connects with the upper end of passageway bridge by screw thread.The lower end of hydrocyclone main body connects with passageway bridge by screw thread.The lower end of passageway bridge connects with plunger by screw thread.The lower end of plunger connects by the upper end of screw thread with whole tube pump plunger.The lower end of bush pump pump barrel connects with the bush pump pump barrel by screw thread.The lower end of bush pump pump barrel connects with whole tube pump pump barrel by screw thread, and the whole tube pump pump barrel that is enclosed within whole tube pump pump barrel outside simultaneously also connects with the lower end of bush pump pump barrel by screw thread.The upper end of passageway bridge connects with whole tube pump pump barrel and whole tube pump pump barrel by screw thread.Connected plunger between bush pump plunger and whole tube pump plunger, the lower end of passageway bridge connects with packer by screw thread.The advantage of this device is the continuous separation of oil water mixture realization that can guarantee in the pit shaft, operating principle is simple, having oil-water separation preferably simultaneously, is can utilize principle of hydraulic cyclone to realize the technological break-through that underground oil-water separates at rod-pumped well in the world at present.
Description of drawings: Fig. 1 is the utility model structure diagram.
The specific embodiment: basis is novel mainly to be made up of on-off connector 1, bush pump plunger 2, bush pump pump barrel 3, hydrocyclone housing 4, hydrocyclone main body 5, bush pump pump barrel 6, bush pump plunger 7, passageway bridge 8, plunger 9, whole tube pump pump barrel 10, whole tube pump plunger 11, whole tube pump pump barrel 12, passageway bridge 13, packer 14.Wherein on-off connector 1 lower end connects by the upper end of screw thread with bush pump plunger 2.Thread connection is passed through in the upper end of the lower end of bush pump plunger 2 and hydrocyclone housing 4.Hydrocyclone housing 4 is to be welded to connect with hydrocyclone main body 5, and the lower end of hydrocyclone housing 4 connects by the upper end of screw thread with bush pump plunger 7.The lower end of bush pump plunger 7 connects by the upper end of screw thread with passageway bridge 8.The lower end of hydrocyclone main body 5 connects with passageway bridge 8 by screw thread.The lower end of passageway bridge 8 connects with plunger 9 by screw thread.The lower end of plunger 9 connects by the upper end of screw thread with whole tube pump plunger 11.The lower end of bush pump pump barrel 3 connects with bush pump pump barrel 6 by screw thread.The lower end of bush pump pump barrel 6 connects with whole tube pump pump barrel 10 by screw thread, and the whole tube pump pump barrel 12 that is enclosed within whole tube pump pump barrel 10 outsides simultaneously also connects with the lower end of bush pump pump barrel 6 by screw thread.The upper end of passageway bridge 13 connects with whole tube pump pump barrel 10 and whole tube pump pump barrel 12 by screw thread.Connected plunger 9 between bush pump plunger 7 and whole tube pump plunger 11, the lower end of passageway bridge 13 connects with packer 14 by screw thread.
The operating principle of oily-water seperating equipment is under the situation of same stroke under the continuous liquid supply oil pumping well, and the volume that whole tube pump plunger 11 is discharged liquid just is the twice that plunger 9 is discharged liquid volume.The liquid that pump is once sucked is discharged half volume in upstroke, down stroke also can be discharged half volume simultaneously, and two bush pumps seal the two ends up and down of hydrocyclone as movable sealing, guarantee that liquid enters from the tangential inlet of hydrocyclone, realize that the underground oil-water mixture separates continuously.On-off connector 1 connected with sucker rod when oily-water seperating equipment was gone into the well under the continuous liquid supply oil pumping well.The upper end of bush pump pump barrel 3 connects with oil pipe by screw thread.Packer 14 separates extraction layer above it and following implanted layer.Oil water mixture in the extraction layer is by passageway bridge 13, be pumped in the whole tube of the continuous liquid supply oil well pump pump pump barrel 10, during upstroke the oil water mixture of half volume by passageway bridge 8 and hydrocyclone housing 4 and hydrocyclone main body 5 annular space and enter in the hydrocyclone from the tangential inlet of hydrocyclone main body 5, isolated low moisture crude oil is given rise to ground, and isolated water is recycled into implanted layer by annular space, the passageway bridge 13 of passageway bridge 8, whole tube pump pump barrel 10 and whole tube pump 12 downwards in hydrocyclone main body 5.
